Fermentation pot refers to a vessel for the production and storage of fermented food. The vessel is made of ceramic or stoneware and has an annular recess around the opening. This is filled with water and a lid is used that dips into the water-filled groove. This enables fermentation gases to escape and prevents the penetration of oxygen and undesirable foreign substances such as dirt or bacteria and mold .
Weight discs made of stone or ceramic are used to keep the solid parts (mostly herb) under the surface of the liquid.
